An airline has found about 8% of its passengers request vegetarian meals. On a flight with 150 passengers the airline has 14 vegetarian dinners available. What's the probability that it will be short of vegetarian dinners? (hint: Let X be the number of vegetarians. Identify a probability model for X. Write a probability expression for X that reflects "Short of vegetarian dinners" and compute.)
